Description of problem:
This might indicate some bug in the partition table reading code.

I have a cheap usb key (sandisk mini cruzer 128M - SDCZ2-128)
After buying the key, I noticed that it would cause
a kernel crash in mandrake but work under redhat.
Switched mandrake for redhat-9.

Lately, I updated to kernel 2.4.20-28.[789] and
got the same crashes as Mandrake.  I googled for
solutions and found a small message saying
that making two partitions sometimes helps.

I rebooted the old kernel, ran fdisk to create two
partitions instead of just one.  Now my key seems to 
work everywhere (mandrake, redhat including 2.4.20-28).

Question: is there a bug somewhere 
in the partition table reading?

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
I tried this using 
- A fujitsu S4542 laptop running RH7.3  (P3m-600M)
- A dell precision 340 (P4-1.8G-Intel850) running RH8.0
- A shuttle SS51G (P4-2G-SIS651+962)  [usb2]

1. Get a USB key Sandisk Mini Cruzer 128M  (SDCZ2-128)
2. Plug with kernel 2.4.20-28.[789]  (kernel crash)
3. Plug with kernel 2.4.20-27.[789]  (works!)
4. Repartition with fdisk.
     - one vfat partition with 249 cylinders
     - one ext2 partition with 1 cylinder (512Kb)
5. Plug with kernel 2.4.20-28.[789]  (works now!)

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
